Maximum rate of acquiring digitised full waveform data is 120KHz. If a higher rate is used then the waveform data will record for every other emitted pulse. But the SCN files will still be recorded at the high rate.

Pulse length (sampling rate) should be chosen based on the maximum height of targets in the area. E.G. if all low lying targets then there is no point using 256 samples at 1 ns - better to use 128 at 1 ns.

No changes to the calibration flights except to collect FW data. Only change to the processing is to find the timing offset between FW and discrete points.

Pre-trigger - like a buffer zone to record digitised samples before the first return. Default is 5m.

Waveform and discrete data use different scalers for the intensity values and so will result in different intensities.

AGC is constant for a pulse - so the same value is used for the entire waveform

There is a slight delay between SCN files and waveform files being recorded (< 1 second). This may result in first few points not having waveform data.
